Agile Software Development

What is Agile?

And

How are we implementing Agile?


Origins of agile l.jpg

Origins of Agile

  • Agile Software Development is heavily influenced by Lean

  • Lean was born as part of the industrial renaissance of Japanese manufacturing after the second world war.

  • During that period Dr. Demming went to Japan and kept talking about his ideas around management and quality. His message to the Japanese corporate world was:

    • Improving quality will reduce expenses while increasing productivity and market share.

We are uncovering better ways of developing software by doing it and helping others do it.

Through this work we have come to value:

Individuals and interactions over Processes and tools

Working software over Comprehensive documentation

Customer collaboration over Contract negotiation

Responding to change over Following a plan

That is, while there is value in the items on the right, we value the items on the left more.
